11.5 Use of the chainsaw in the tree

An analysis of accidents with these chainsaws during tree
pruning work shows that the main cause is improper one-
handed use of the chainsaw. In most accidents, users do not
adopt a secured working position that allows them to hold the
chainsaw by both handles, resulting in an increased danger
of injury from the following:
• Lack of a firm grip on the kick-back of the chainsaw.
• Lack of control of the chainsaw, making it easier for it to
come into contact with climbing ropes and with the user's
body (especially the left hand and arm).
• Loss of control due to an unsafe working position and thus
contact with the chainsaw (unexpected movements while
working with the chainsaw).
11.6 Secured working position for two-handed
use
In order to be able to hold the chainsaw with both hands,
users should always try to adopt a secured working position,
guiding the saw as follows:
• at waist height when sawing horizontal pieces.
• at stomach height when sawing vertical pieces.
If the user is working close to the vertically running trunk with low
lateral forces to the working position, a secure foothold could
be sufficient for a safe working position. However, as soon as
users move away from the trunk, they must take additional meas-
ures to reduce or counteract the increasing lateral forces, e.g.
by diverting the main rope via an additional suspension device
or by using an adjustable sling leading from the harness to an
additional suspension device (Figs. 15 and 16).
11.6.1 Starting the tree pruning saw on the tree
When starting the chainsaw in the tree, the user should:
• activate the chain brake before starting (push the front
hand guard (3) forward).
• hold the chainsaw to the left or right of the body when
starting:
- Holding the chainsaw on the left side with the left hand
on the front handle and pushing the chainsaw away
from the body while holding the throw-on rope in the
right hand.
- Holding the chainsaw on the right side with the right
hand on one of the two handles and pushing the chain-
saw away from the body while holding the throw-on
rope in the left hand.
The chain brake should always be activated before lowering
the running chainsaw by its suspension cable.

Before difficult sawing work, the user should always make
sure that the chainsaw has sufficient fuel.
11.6.2 One-handed use of the chainsaw
Users should not use chainsaws for tree care one-handed in
unstable working positions or instead of a hand saw for saw-
ing off small diameter branch tips.
Chainsaws for tree pruning should only be used one-handed
when
a. it is not possible for users to obtain a working position that
allows two-handed use.
b. it is necessary to secure the working position with one
hand.
c. the chainsaw is used in a fully extended position, at right
angles to and out of line with the user's body.
Users should never:
• Saw with the kick-back area at the tip of the guide rail (2)
of the chainsaw.
• Holding on to the branch they are sawing on.
• Try to catch falling parts.
11.6.3 Release a jammed chainsaw
If the chainsaw becomes jammed during cutting, the user
should:
1. Switch off the chainsaw and attach it securely towards
the inside of the tree (i.e. towards the tree trunk) or to a
separate tool rope.
2. Pull the chainsaw out of the notch while lifting the
branch as far as necessary,
3. If necessary, use a handsaw or second chainsaw to
loosen the jammed chainsaw by cutting at least 30 cm
away from the jammed chainsaw.
Regardless of whether a hand saw or a chainsaw is used to
release a trapped chainsaw, the cuts to release the chainsaw
should always be made on the outside (towards the tips of
the branches) so that the chainsaw does not get carried away
with the sawn-off parts and further complicate the situation.

12. Transport

• Always use the guide rail cover (21) when transporting.
• Switch off the chainsaw before any transport, even over
short distances. Secure the machine against tipping over
during transport (including in vehicles) to prevent fuel loss,
damage or injury.
• Activate the chain brake (push the front hand guard (3)
forward).
